Patented Sept. 8, 1953 UNITED STATES TENT OFFICE LOCKER CONSTRUCTION John B. OConnor, Aurora, Ill., assignor to Lyon Metal Products, Incorporated, Aurora, Ill., a corporation of Illinois (Cl. S12-329) 7 Claims.

This invention relates to metal lockers.

The present application is a division of my prior filed parent application Serial No. 673,566, filed May 31, 1946, and now Patent No. 2,568,592, dated September 18, 1951, reference to the specication and drawings of which is made for the particular type of handle, including both broad and specific claims thereto, and also to a divisional application Serial No. 31,380 (now Patent No. 2,595,473) filed concurrently herewith, likewise showing the details of the locking mechanism and handle in association with the locker, wherein speciiic and broad claims are made to the specific type of locking means. The claims of the present application are drawn to the locker construction, including details of construction of a multi-compartment type of locker.

One of the objects of the present invention resides in providing an attachable support; which may be assembled to the side members of a locker construction and to the front corner posts of the cabinet at a zone intermediate the vertical height of the cabinet, which detachable support is adapted not only to form a support for the front edge of a removable shelf but which is likewise adapted to form a horizontal partition at the front of the cabinet between the front corner posts to form a dividing partition for the upper and lower doors.

Another object of the invention resides in providing a locker or cabinet construction which utilizes an integral front framework including legs to which are connected a pair of sheet metal sides, a sheet metal bottom and a sheet metal top, and a sheet metal rear, the junction of the rear with the top and the sides and the bottom Aforming such a rigid construction that the necessity for a rear rigid framework for the cabinet, corresponding to the front rigid framework, is eliminated.

These and other objects of the invention will be Eapparent from a perusal of the following specification, when taken in connection with the accompanying drawings, wherein:

Figure 17 is a perspective view of the hinge members which pivot the door to the frame of the locker.

Referring now to the drawings in detail, and particularly with reference to Figure 1, it will be noted that the locker comprises a front frame member of integral construction which includes the two vertical angle iron side pieces 2 and 4, the integral bottom cross angle 6 and the top cross angle 8. The cross bars E and 8 are preferably united by welding. The two side angles 2 and 4 extend downwardly at their lower ends to provide the integrally formed feet I0 and l2. suitably attached to the front upstanding vertical frame members 2 and 4 as at I4 and I5, as by rivets or self-tapping screws or by bolts and nuts, is a side panel 20 formed of sheet metal. The marginal flange portion I8 of this panel 20 underlies the angle portion 24 of the vertical angle iron 2. Similarly another side panel 26 has a forward flanged portion 28 which is fixed to and lies beneath a corresponding side flange of the vertical corner bar 4. A sheet metal back 34 has right angle flanges 36 and 38 which are fastened to flange portions 40 and 42 of the side panels 20 and 26. The top 44 is provided with four depending border flanges 46, 48, 50 and 52 which are fastened in any suitable manner, as by bolts and nuts 53, 54, 56 etc. The top depending ange 46 is not bolted or fastened to the top cross bar 8 of the door frame. However its bottom edge 45 rests upon an inwardly eX- tending integral flange 9 of the top frame, as shown in Figure 4. The other side wall portions of the top are aixed to the side and back panels. In the same manner a sheet metal bottom 58 is provided with depending anges 60, 62, and two similar ilanges on the other side, not shown in Figure 3. The front depending flange 60 of this bottom 58 lies inwardly of the front face of the bottom cross angle 6 and its bottom edge lies upon an inwardly extending horizontal flange of the bottom cross bar 6, as shown in Figure 4. The other flanges of the bottom are bolted as at 64 and 66 and 68 to the side and rear panels of the locker.

The locker preferably includes an intermediate shelf l having depending flanges 12, 74, 'I6 and a flange opposite the flange 14, not shown. The front depending flange '|2 has an inwardly and upwardly bent tongue 80 for finish and the two side flanges 'I4 and itsv opposite one terminate as at 82, short of the rear depending ange l5, so vas to clear the two` flange walls 36 and 38 of the rear panel 34. The shelf 10 is bolted as at 86 and 08 to the two side panels 20 and 26. If

desired, hooks 00, 62, and 94 may be attached to the back walls at 96 and 98 or to the side panels or to the depending side anges la of the shelf 10. Thus there is provided a rectangular structure formed of the panels and the front rigid frame member 2, 4, 6 and 8.

The front frame member comprises front legs |0 and l2 while the rear legs are formed by a pair of relatively short corner angle uprights |00 which are adequately bolted to the corners of the side and back panels 20, 26 and 35, as

shown in Figures 4 and 5.

Preferably the bottoms of the front legs l0 and |2 and the rear legs |00 are provided with adjustable legs. To this end, one of the iianges of the bottom portions of the legs l0 and l2 and the rear legs |00 is provided with a platet like reinforcement or spacing member |0005, see Fig. 16, and a bolt hole |00e is drilled or otherwise provided both through this plate and through the flange of the leg to which it is welded. In addition, there is provided a foot section |00b which is preferably of the same width as the flange |00 to which the plate |00a is welded and which has a vertically elongated slot |00d, and this section |001) in turn is provided with a normally disposed, hat, plate-like foot section |000 of the door |02. The opposite vertical edge of the door is provided with an inwardly extending flange ||4, see Figure 6, which in turn has a right angled, relatively shorter flange H6 that preferably lies parallel to and in the plane of the flange H2. A pair of hinged leaves HB are spot welded as at |20 to the upper vertical door frame si. In addition, another pair of leaves |22 is bolted as at |24 to the vertical liange H0. The end |26 of one of the leaves |22 is bent around the flange ||6 and terminates in a short iiange |28 that covers the vertical end of the flange i i These hinge members are formed as shown in Figure 17 and a pivot pin |30 passes through the spaced loops or barrels of the hinges and after they are assembled the pin is held in position by means of indents |32 and |34 formed in portions of the barrels of the leaves ||0 whereby to hold the hinges assembled. This is a type of hidden hinge that covers the raw edge of the flange 56 and lies iiush with the bulb 4' of angle l of the framework.

At the opening |08 of the door |02 the front wall is provided with integral, inwardly extending tabs or ears |36 and |38, see Figure 3. Both of these ears are perforated to receive rubber bumpers.

The slot |08 is adapted to receive a shiftable handle mechanism comprising a front plate 200, see FigureY l, which is mounted on the iront of the door |02 and is capable of sliding vertically with respect to the opening |00 of the door, all as described and claimed in the parent application Serial No. 673,566, filed May 31, 1945, and also in the divisional application iiled concurrently herewith. This handle plate 200 has portions rigid therewith which project through the opening |08 of the door |02 and connect with a housing |18, see Fig. 6, which in turn is rigidly connected to a vertically extending latch carrying bar or channel bar |10 which channel bar in turn carries an elongated latch 244 adapted to engage behind a shoulder |68 of a keeper |613, and which keeper has a camming or wiping surface |66 adjacent to the locking shoulder |60 of the keeper. This keeper |60 has a flange |55 welded as at |51 to the rear face of the front flange of the rigid corner angle iron l so that the keeper or keepers are constantly in position to register with openings |48 in the rear wall of an integral guideway formed by the ange H0 on the rear of the door and the ange H2 bent at right angles thereto to form a vertical guidedirection of the feet |000 and |000l are in oppo- Y sition to one another, whereby to provide greater stability for the cabinet.

Cooperating with the integral door frame member 2, 4, 6 and S of the locker, and which member is shown in Figure 3, is a. door |02 of sheet metal, also shown in Figure 3. This door member has an upper, inwardly extending horizontal flange |04 and a bottom inwardly extending horizontal ange |06, see Figure 2. In addition, at its front right hand side it is provided with an elongated rectangular opening |03. It likewise has a front vertical inwardly extending iiange ||0 which in turn, as shown in Figure 2, is provided with an inwardly extending short flange ||2 that parallels the plane of the door |02. This flange ||2 is spaced from the plane way to receive the channel bar |10, all as shown and described and claimed in my parent and concurrently filed divisional applications.

In the operation of such type of door, upon the closure of the door the iiexible latch 20d will wipe past the camming surface |66 of the keeper and snap lock behind the shoulder |66 thereof, whereby to snap lock the door in locked position. vertically sliding the handle plate 200 with respect to .the front of the door will raise the lower edge of the latch 244 free of the locking shoulder |60 to release the door to opening movement. A lock 268, described and claimed in the parent application and also in the concurrently iiled divisional application, is mounted on the rear face -of the door and is adapted to cooperate with certain stop mechanism carried by the rear of the channel bar, and not herein shown, whereby to prevent the sliding movement of the handle plate 200 of the door and consequently to prevent the release of the latch so that the snap locked condition of the door cannot be re- 5.. leased, and hence the door will remain locked by the manually operable lock 214. This lock .214 has a key fitting barrel. which projects. through the front of the door, as shown in Figure 1.

The details of the locking mechanism per se and the manner in which it cooperates with the door are not herein further shown in detail since the same forms the subject matter of my parent application and the separate divisional application thereof led, wherein the invention resides in the constructional features of the locker independently of the locking mechanism.

In Figures 1 to 6 I have illustrated a locker wherein there is a single compartment provided with an intermediate shelf, the front of the locker or cabinet being closed by a single door. In Figures 7 to 10 inclusive .I have provided `a locker or cabinet having a vertical series of corn-- partments each provided with its own door .and each door having a locking construction identical with that described in my .parent application. In providing a multicompartment locker having. a plurality of doors, I provide a detachable .support member 216, see Figure 10. This support member has outwardly and rearwardly extending arms 218 and 280 which are suitably perforated to receive bolts. The forward portion of this partition member 211: is substantially flat and is cut away at its ends as at 282 .and .284 to avoid the front portions of the vertical corner strips 2 and 4 ofthe rigid front frame members. In this construction these front frame members are provided with slotted .portions or rabutments 1286 and 288, see Figure 9, which receive the corner portions of the support portion 216 formed by the cutouts 282 and 284, whereby the front edge is supported at 286 and 288 and whereby the rear edge of the member 216 is supported by the bolts 292 and 294 which engage the side panels 28 and :26. It will .be noted .that these side panels and the rear ,panel 34 in this construction extend the entire height of the multidoored locker. The support member 216, as shown in Figures 8 and 10,`has aninwardly and downwardly extending interior .iiange .29.6. A horizontal partition member Iand shelf 298,- see Figure 8, has side depending flanges .388, .and an opposite one, not shown, and a .iront depending flange 384, see Figure 8, and a rear vdepending flange 386. The side flanges, like 3118, are held to the opposed side panels '28 and 26 by means of bolts 292 and 388. The front depending iiange 384 of the shelf 298 has a countersunk shoulder 312 which rests directly upon the right Aangled internal corner formed by the intersection of the horizontal flange 298 and the vertical flange 296 of the partition member or support .216 and is spot welded to the member 216 .as .at .211, thereby supporting the same at the iront. vThis horizontal partition member 288 forms a bottom for the upper compartment and a top for the next lower compartment. The upperpart of the vertical iiange 384 of this partition .298 above the ange 290 and the flange 29.6 .of the .front partition member 21.6 act as a. stop .for the bottom and top edges respectively of the doors. lIn .the multiple tier type of locker the doors are .preferably fitted with locks but nothandles. In'Figures 11, 12 and 13 I haveshown .modifications oi the cabinet or locker construction wherein a slanting or sloping top attachment .3.14 is .provided. The sloping top is .preferably .designed as a separate unit thatmay be attached .to .any flat top locker of similar size, or .if thelockeris purchased .with a sloping top vand later -the user 75 prefers a .flat top, cthe sloping top .may be removed. As shown, this top member 13.14 has lateral depending flanges 316, there .being an identical one on .the other side, and which also has arear Avertical wall 31.1 having .two vertically extending flanges 318, only one being sho-wn, which are bolted to triangular side pieces 328, there being an identical sidepiece on the opposite side not shown,as by means ofbolts 324 and 326, see .Figure 15. If desired, these bolt fastenings may be replaced .by spot welding. In addition, the bottom of these two side .members 328 and the rear wall are bolted as at 328, .330 and 331 to the top edge of the rear panel y34. The lower edge 332 of these side triangular .members Y2li is disposed inside of the top edge 344 .of the panel 2.8 and also, not shown, .disposed inside of the top .edge of kthe opposite .side panel. The 'top frame membenasshown in Figure 13, has a horizontal portion 9 .disposed at .right angles tothe vertical portion 8 of said frame member, and the lower end of .a front frame 334 of top 314 rests upon this .horizontal ange 9 and against the vertical portion 8 thereof. The rear lower corner of the triangularportion 326 is cut away as .at 338, see Figurel, to allow the sloping top to be easily inserted into the top of the locker. In addition .these triangular side members 328 are slitted and are provided with three preferably outwardly bent ears 338, 340 and 342, which are bent slightly outwardly and overlie the'upper edge 344 of the side panel "20 whereby these triangular three side panels 328 of the tcp have portions straddling the upper edge of the side portions '28, see Figure 15.

In the construction shown in Figures 11, 12 and 13, which possibly is a preferred construction, instead of `providing the sides of the top with slotted integral lugs 338, 348 and 342, I secure gauge clips 358 and 352, see Figure 13, to the opposite side members 328 as by Welding. Preferably these clips are of 24-gauge sheet metal and are secured by the spot welds 358 and 363. These .clips have downwardly projecting portions 362 and .364 which are adapted to project outside of the .top edge of the side portions28 of the cabinet in the manner shown `in Figures ll, 12 and .13, and the front iianges or skirt '334 of the top, as shown, will rest on the horizontal iiange 9 and .against the vertical flange 8 of the top portion.

In short, except for the manner .of forming thegauge clips separately and then welding them onto the side members ofthe top, the constructions of 'Figures "14 and 15 and the constructions of Figures 11 to '13 .are substantially identical. In any 'instance' it Will be appreciated that by means of the :foregoing construction a cabinet may be sold with either a flat top or with a sloping top, together with means for quickly and easily attaching the sloping top-Ain position.. It will be appreciated that 'the sloping top eliminates dirt and preventsthe unsightly accumulation of rubbish, packages, or other refuse on the top of the locker.

fObviously the invention is not limited to the speciiic details of construction disclosed herein but is capable .of othermodications and changes without departing from the spirit and scope of the `appended claims.
